Xcode playground not executing functions

Question

I created a new playground and I add simple function but the function is never been call:

var str = "New playground"

func hello()
{
    print("Hello, World")
}

Any of you knows why the function is not been call ?

I'll really appreciate your help

Because you didn't call the function. Just call it:

func hello()
{
    print("Hello, World")
}

hello()

I add it the line with hello() but I get the error : Use of unresolved identifier 'hello'

Note: The function needs to be declared before its call, like this example is written.

not working Expected '{' in body of function declaration

Also, If you are calling the method before its implementation, the Swift Playground wouldn't allow you to do that, and errors out as below

Use of unresolved identifier 'hello'

WRONG ORDER:

hello()
func hello()
{
    print("Hello, World")
}

RIGHT ORDER

func hello()
{
    print("Hello, World")
}
hello()
